Theres a nice piece about her here . . . http://www.npr.org/2011/11/27/142664182/most-beautiful-woman-by-day-inventor-by-night
And her character also makes an occasional appearance in Nitrozac's comic Strips 'After y2k' and 'The Joy Of tech' :) - Seems she was a lot more 'geek' than actress, and when the Germans started targeting passenger liners, she felt the need to contribute and make something...

While studying electrical engineering, the story of Tesla inventing rotating magnetic field told by our professor teaching electrical machines fascinated me. Since then Tesla is my hero and I believe in the same as you have told.

Nice summary.I used to teach spread spectrum technology and used the Hedy Lamarr link to awaken slumbering students. I became intrigued and wrote a book on the inventors and the technology. Like you I found lots of prior art and pondered on the real contribution of the Secret Communication System to current frequency hopping.
I did miss Zenneck’s book Wireless Telegraphy (English version) in my searches which is pity. My book is called 'Spread Spectrum: Hedy Lamarr and the mobile phone. More details at http://www.robsbookshop.com/page31.html

This is a very good finding, may be as Sahrps_eng is pointing there will be many hidden application and ideas like this will be there, if found that as well can be shared and discussed, but this is a very nice match that very well simulates the FHSS.

You couldn't write this stuff!
I think that there are many fascinating revelations to be made when comparing history as written by say, the Germans, French and Americans.
In many cases patents were independently awarded for the same things in different countries, there was no Internet to Google in those days.
How many opportunities are missed because today's English speakers can't access the work of Hungarians, Japanese and Chinese scientists and engineers?
Even now many don't bother to translate work into English, so we only get to see information filtered through the marketing channel.
Imagine if the only way people knew about us was by reading EET?
